A team of scientists working at Lawrence Berkeley National Laboratory (Berkeley Lab) has discovered a new form of the human-made element mendelevium. The newly created isotope, mendelevium-244, is the ...

Researchers may have just spotted the elusive, ephemeral nucleus of nitrogen-9 for the first time. With seven protons and two neutrons, the lopsided atomic nucleus of nitrogen-9 pushes the limits of ...

The isotope lead-208 was predicted to be extremely stable and perfectly spherical because of the “magic” numbers of electrons and protons orbiting its nucleus. When researchers blasted lead-208 with ...

Scientists have created six new isotopes of the superheavy elements, reaching in an unbroken chain of decays from element 114 down to rutherfordium. The discovery is a major step toward understanding ...

Artemis Spyrou receives funding from the National Science Foundation and the Department of Energy/National Nuclear Security Administration. When you hear the term “radioactive” you likely think “bad ...

A few years ago, a group of physicists created an unusual, never-before-seen subatomic particle. Using a particle accelerator at Riken, a Japanese research institute, they slammed streams of calcium ...

The nuclei that exist inside atoms of elements readily found in nature — such as carbon, oxygen, aluminum, iron, copper and gold — consist of fixed combinations of protons and neutrons. But if these ...
